[目的] 研究浙江省水资源生态足迹时空格局,并对浙江省及各市水资源可持续利用水平进行评价,为区域发展和相关政策的制定提供必要的理论指导和依据. [方法] 以生态足迹理论为基础,运用水资源生态足迹和生态承载力模型,核算浙江省及其各市水资源生态足迹和生态承载力. [结果] 从时间序列看,2003—2013年浙江省整体水资源生态足迹呈较小波动的上升趋势;水资源生态承载力波动较大;人均水资源生态量均为盈余,且整体为上升趋势;水资源利用处于安全状态;水资源利用效率逐步提高.从空间差异看:浙江省各市水资源生态足迹可分为高值、中值和低值3个级别;水资源生态承载力和人均水资源量均呈自西南向东北递减格局;南部地区水资源生态安全程度高于北部地区;东部地区水资源利用效率高于西部和北部地区. [结论] 浙江省整体水资源可持续利用水平逐步提高,但内部差异显著.为提高水资源利用科学化水平,浙江省及其各市应从发展阶段和发展目标出发,合理调整产业结构,建设相关水利工程设施,加强水资源循环利用,增强水资源保障.
[Objective] The objective of this study is to investigate the spatial-temporal pattern of water resources ecological footprint and evaluate the sustainable utilization of water resources in Zhejiang Province in order to provide theoretical basis for the regional development and policy making. [Methods] Based on the theory of ecological footprint, this paper calculated the ecological footprint and the ecological carrying capacity of the water resources in Zhejiang Province. [Results] From 2003 to 2013, the ecological footprint of the water resources showed an upward trend with a slight fluctuation, while the ecological carrying capacity of the water resources fluctuated greatly. The water resources per capital was surplus in the research area, and showed an increasing trend. The utilization of the water resources was secure, as the utilization efficiency of the water resources was increasing year by year. Ecological footprint of the water resources in all cities were divided into three levels: high, medium and low in Zhejiang Province. The ecological carrying capacity of the water resources and the water resources per capital showed a decreasing pattern from southwest to northeast in research areas. The water resources ecological security in southern regional was higher than that in the northern regions, while the utilization efficiency of the water resources in eastern region was higher than that in the western and northern regions. [Conclusion] Although the sustainable utilization of water resources in Zhejiang Province is increasing, great differences existe among different cities. Government should take relevant measures such as reasonable adjustment of industrial structure, construction of water conservancy facilities, intensification of water resources recycling and strengthen of water resources security, to improve the efficiency of water resources using based on development stages and goals.
